Alternate New Vegas Timelines

Hey guys what do you think some alternate timeline scenarios would be in the world of New Vegas? Like what would happen if the Legion won the first battle of the Hoover Dam, or what would happen if the Courier died when shot by Benny? Would just like to hear some thoughts

if the legion won the first battle at hoover dam, the Courier might still be alive, and the focus may still be on New Vegas and Mr. House's bots vs Caesar's Legion. if the Courier died, i don't know what kind of character you would play as, you could possibly play as an NCR citizen, but idk.
